Production of the enzyme naringinase by Aspergillus niger.
The formation of naringinase, a glycolytic enzyme produced by Aspergillus niger, is repressed by glucose. Production of the enzyme is decreased below pH 4.0 and is stimulated by the presence of substrate. Fermentation conditions are described which cause the formation of the enzyme in approximately a fivefold greater concentration than that previously described.
متن کاملSynthesis of malformin by an enzyme preparation from Aspergillus niger.
Yukioka, M. (University of Hawaii, Honolulu), and T. Winnick. Synthesis of malformin by an enzyme preparation from Aspergillus niger. J. Bacteriol. 91:2237-2244. 1966.-An enzyme fraction derived from disrupted Aspergillus cells was able to utilize each of the component labeled amino acids of malformin for the synthesis of this cyclic pentapeptide. The process was stimulated by adenosine triphos...
متن کاملIsolation and characterization of inositol-containing glycosphingolipids from Aspergillus niger.
The glycophosphosphingolipids are a group of sphingolipids characterized by the presence of equimolar amounts of long-chain base and fatty acid (ceramide) and containing either one or two mol of inositol phosphate per mol of lipid. From one to several mol of sugar are also present. Glycophosphosphingolipids have been isolated from both plant and fungal sources. Work in this area had for years b...
متن کاملIsolation and molecular identification of bacteria producing alkaline phosphatase enzyme from environmental sources
Alkaline phosphatase (ortho phosphate, monoester hydrolase phosphoinositide E. C. 3.1.3.1) is a non-specific metalloproteinase enzyme that is located inside periplasmic space of bacteria. This enzyme is used to measure freshwater sediment in genetic engineering for cleaning water. Isolation and molecular identification of the bacteria producing alkaline phosphatase and comparison of its product...
متن کاملProduction kinetics and characterization of pectinase enzyme from Aspergillus niger
Food grade pectinases from Aspergillus niger are predominantly used as processing aids in industries. In the present investigation, efforts towards standardization for pilot scale production of pectinase enzyme from A. niger were made. The crude enzyme was studied for its kinetics to optimize substrate concentration and processing parameters on the basis of polygalacturonic activity. Km (Michae...
